Title: Anode sludge treatment to separate copper and nickel values
IPC: C22B15/00
Filed: 1970-06-11
Abstract: Decomposition of copper electrolysis anode sludge by (A) extraction of a Cu soln. poor in Ni and (B) the extraction of appreciable fractions of Ni from the anode sludge; the decomposition being in the presence of oxygen or oxygen-contg. gas, in an autoclave at >=5 atm. gauge and above the b.pt. of the soln. Stage (A) is pref. at is not >110 degrees C with admission of at least the amt. of supplementary oxygen, e.g. air, required to dissolve the soluble Cu fractions.
